AUTOMATIC WATER-FEED FOR ACETYLENE-GAS GENERATORS.

Specification of Letters Patent.

Patented May '7, 1907.

Application filed September 20,1905. Serial No. 279.314.

To all whom, it wz/cty concern.-

Be it known that I, HERBERT GORDON SCOTT, a subject of the King of Great Britain and Ireland, and a resident of 56 Liverpool street, Darlinghurst, Sydney, in the State of New South Wales, Commonwealth of Australia, have invented a certain new and use ful Automatic Water-Feed to AcetyleneGas Generators, of which the following is a specification.

This invention relates to that class of acety lene generators where the gas is generated in chambers separate from the gas holder, the water being fed, as required, to the generating chamber or chambers that contain the carbid of calcium, and from whence the gas, when it is evolved, will escape into the gas holder.

If the plant is supplied with a water purifying appliance, and such appliance cmbraces a rising and falling bell the novel automatic water feed may be adapted either to the bell of the purifier or to the bell of the gas holder.

In the accompanying drawings the invention is shown applied to the gas holder, in the well of which are placed the carbid or generating chambers.

Figure 1 is a plan view of the'well of a gas holder, with the bell removed, the position of the bell being shown by the circular dotted line. Fig: 2 is a vertical section of the well and bell of a gas holder, the section being taken on the line 1-2 of Fig. 1. Fig: 3 is a partial plan on a larger scale, of the top of the bell and well, with the top of one of the hand screw appliances for adjusting the feed to one or other of the generators that contain the carbid. Fig: 4 is a vertical section of the same. Fig: 5 shows the front valve, which is cut away in the section shown at Fig: 2. Fig: 6 is a view of the front valve, on an enlarged scale, and shows how the valves are I operated by the descent of the bell of the gas holder, when the gas is being consumed faster than it is being generated.

A is the well of a gas holder, at the bottom of which are placed three carbid chambers, or generators, B, C, D.

E is the bell of the gas holder, which rises or falls, as the gas is generated or consumed.

On the floor of the well A are placed three platforms of different heights, F, G, H on which are bolted brackets or standards F, G, H which serve a double purpose. The

standards support the fulcrumsf, g, h of the levers f, g, h, which operate the spindles or rods J, K, L, of the valves J, K, L. Either the valves or the levers f, g, it must be weighted, so as to insure that the valves shall drop on to their seats when the levers are released from downward pressure. That part of the bell E which is adjacent to two of the valves (in this case, valves K, L) is recessed, as shown at b, Fig: 2, and 6, Figs: 5 &

6. These recesses have a special function.

The depth of the recess varies directly as the height of the platform upon which the adj acent standard is mounted, e. g. platform G being the highest, the adjacent recess 7) is the deepest or the platform H being of medium height, the adjacent recess 1) is of medium depth. Thus, when the bell descends, owing to the consumption of gas, the bottom edge of the bell will impinge against and depress the long arm or tail end of the lever f and thus open the valve J; the bottom of the recess b will impinge against and depress the long arm or tail end of the lever it thus opening the valve L, and the bottom of the recess 6 will impinge against and depress the long arm or tail end of the lever 9, thus opening the valve K. The opening of the valves J, K, L would, in this case, be nearly or quite simultaneous. But it is desirable that the opening of the valves should. be susceptible to a time adjustment so that either one of the carbid chambers or generators may be brought into action before either or both of the others. Therefore special appliances have been devised which are adapted to attain that end. From the top of the bell E depend three tubes M, N, 0, shown in Figs: 2, 4 and 5, provided with nuts m, n, (0 not shown in the drawing) at their top ends. Traversing these nuts are screwed rods l N, O adapted to be screwed down by the handles m, n (0 not shown in the drawing) whereby the impinging points at the bottom edge of the bell, or at the bottoms of the recesses b, b may be artificially extended, and either valve be opened before the others, or two may be made to open at the same time, leaving one in reserve; 0. 9. if the rods N, O be screwed down until their bottom ends coincide with the bottom edge of the bell E, then the valves would be operated in consecutive order, thusthe valve K being adjacent to the highest platform G would be opened first, and then, in consecutive order,

dium platform H, and the valve J, which is adjacent to the lowest platform F.

When either of the valves are opened, the water which is in the well, (to form a Water seal for the bell) will pour through the valve, through the pipe connections P, Q or R into one or other of the generators B, C, D, where it will come in contact with the carbid, and acetylene gas'will be evolved and will rise through the gas pipes S, T, U, toward the top of the water in the well, where it Will be washed, and ascend then into the bell and will cause the bell to rise. The rising of the bell will free any or all the levers f g, h thus clos ing any or all the valves which may have been open, and the valves will then remain closed until such time as the gas in the gas holder is spent, when the bell will descend, as the gas is consumed, and one or other of the valves, as desired, may be opened by the automatic descent of the bell.

Having now described my invention, What I claim as new and desire to secure by Letters Patent is 1. An acetylene gas generator, comprising a casing, a bell, a number of chambers in said casin havin o enin s communicatin withv said casing, valves controlling said openings, platforms of different heights, levers connected to the valves and supported on the platforms, said levers being automatically tripped by the descent of the bell, said bell having notches in its bottom edge of different depths at points which lie over the ends of the levers.

2. An acetylene gas generator comprising a Well, a bell, a number of chambers in said well having openings communicating with the 'well, valves for controlling said openings, platforms of different heights in the well, standards on said platforms, a lever pivoted to each standard and having one end connected to a valve, the other end of said lever extending into the path of the bell, said bell having notches in the bottom edge of its walls adapted to engage the'levers and trip them and means for extending the points in the bottom edge-of the bell, or the notches therein, that impinge upon or engage the levers as the bell descends.

3. An acetylene gas generator comprising a well, a bell, a number of chambers in said well having openings communicating with the well, valves for controlling said 0 enings, platforms of different heights in t e well, standards on said platforms, a leverpivoted to each standard and having one end connected to avalve, the other end of said lever extending into the path of the bell, said bell having notches in the bottom edge of its walls adapted to engage the levers and trip them and means for extending the points in the bottom edge of the bell, or the notches therein that impinge upon or engage the levers as the belldescends, said means consistingof a number of rods and means for adjusting them longitudinally.

In witness whereof I have hereunto set my hand in presence of two witnesses.
